Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Randomisation mentioned but insufficient information about the sequence generation process to permit judgement
Allocation concealment (selection bias)	Unclear risk	Insufficient information to permit judgement
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	‘As‐treated’ analysis done, drop outs reported
Selective reporting (reporting bias)	Unclear risk	Insufficient information to permit judgement
Other bias	Low risk	The study appears to be free of other sources of bias
Blinding (participant)	High risk	Not possible
Blinding (assessor)	Unclear risk	Insufficient information to permit judgement
Were the treatment and control group comparable at entry?	Low risk	No differences reported on baseline characteristics with a potential to influence the effect of the intervention
Was the surveillance active, and of clinically appropriate duration (i.e. at least 3 months post intervention)?	High risk	Only immediately post intervention data, no follow‐up data reported.
